JOURNAL-BRASS.

SPECIFICATION forming part of Letters Iatent No. 301,851, dated July 15, 1884.

' Application filed May 26, 1884. (No model.)

To all whom; it may concern:

Be it known that I, SUMNER A. BEMIs, a citizen of the United States, residing at Springfield, in the county of Hampden and State of Massachusetts, have invented new and useful Improvements in J ourna1-Brasses, of which the following is a specification.

This invention relates to improvements in journal-brasses for car-axle boxes, the object being to provide a brass for said use, having pending wings thereon parallel with the direction of the journal-bearing, and arranged so as not to be in contact with the journal, and provided with an improved saddle-bearing, and means for controlling the flow of oil escaping from the journal, and for facilitating the insertion and withdrawal of the brass into and from the axle-box.

In the drawings forming part of this specification, Figures 1 and 2 are plan views, respectively, of the upper and under sides of a journal-brass embodying my improvements.

.Fig. 3 is a side elevation of the brass, a part of which is cut away on the line mm, Fig. 2.

Fig.4: is an end elevation.

In the drawings, w is the jOurnaLbearing, and a (l d are saddle-bearings over the journal-bearing, the brass herein described and shown being adapted to be used with-a saddle which fits the top side thereof, and has a fiat upper side, against or upon which the top'of the axle-box lies. The said bearing-face a extends between the transverse grooves f f, and said bearing-faces d d incline outwardly from each side of face a, and have thereon the projecting saddle-wings b b, which are adapted to enter recesses in the before-mentioned saddle, whereby the brass A is prevented from sliding endwise under the latter. Two cavities, o 0, are made in the face a, for the purpose of reducing the weight of the brass. By grooving the brass transversely at f f, an upwardlyprojecting finger-piece, c, is formed at each end of the brass, which does not stand above the face a, and consequently does not interfere with any endwise movement of the brass in placing it under the saddle, and provides convenient means for grasping the brass to handle .it, and for placing it in the ax1e-box.'

The extent of the journal-bearing surface .10, 5o longitudinally, is from end to end of the brass, and circumferentially above the lines z, Figs. 2 and 3, and the junction of the vertical and the horizontal lines m m in Fig. 4 represents the location of said lines 2 relative to the lower edges of the sides of the brass A. A curved wing, 22, extends downward from the lower edge of each inclined bearing-face d, and terminating at each end of the brass in the form shown in Figs. 3 and 4, and the inside brass along the edges of the wings to their lowest points, from whence it drops into a proper receptacle in the axle-box. Each end of the brass, from about the line i above the journal-bearing w, is beveled back toward-the '7 5 deepest part of the wings 12, forming the inclined face y, whose lower edge, over the journal-bearing w, terminates at the latter, and each side of the said bearing becomes merged in the curve of the wings c. The effect. of the said inclined face y is to cause the oil which works from between the brass and the journal to follow the downward incline of face y onto the curved edges of the wings '0, following the latter, as above set forth, and dropping clear 8 5 of the journal. "The bosses e on the sides of the wings 1; provide. means for fitting the brass to its place in the axle-box byfiling off said bosses more or less.

What I claim as my invention is- 1. A journal-brass having over its journalbearing 10 the saddle-bearing a, and on each side of the latter an inclined saddle-bearing d, having the wing b thereon, and having the curved downhanging chambered wings t v, the finger-pieces c, and the inclined face yat each end, substantially as set forth. v 2. A journal-brass having the journal-bearing w, the saddle-bearings a d d, the wings b, the inclined face y at each end, communicatthe curved chambered wings 0 v, and the ining with the bearing 10 and the edges of the elined face 7 at each end, communicating with wings 12, substantially as set forth.

- the bearing 10 and the edges of the wings v, SUMNER A.- BEMIS. 5 substantially as set forth. \Vitnesses:

3. Ajournal-brass having thejournal-bear- H. A. GHAPIN, ing 10, the curved chambered wings v '0, and J. D. GARFIELD.
